Abstract: PROBLEM TO BE SOLVED: To reduce noise by driving a bus comprising multiple bits. SOLUTION: A host side device transmits an address signal 17 for reading data from a memory 11 and the memory 11 imports the address signal 17 at a timing of starting of an input clock signal 17. A clock shift part 13 shifts the input clock signal 16 by 1/8 period to form shift clock signals 16-1-16-4 and outputs them to data shift parts 14-1-14-4 respectively. The data shift parts 14-1-14-4 transmits the data signals outputted from the memory part 12 synchronously with the starting of the shift clocks 16-1-16-4. The data signals outputted from the data shift part 14 are outputted by mutually shifted by the 1/8 period of the input clock signal 16 as data signals 18-1-18-4 on respective signal lines of the data bus 18 via an output buffer 15 and transmitted to the host device.
